GEAR CASE (COUNTER ROTATION)
Cross reference the engagement mark and tolerance
calculated in the previous step, and refer to the pinion
gear shim selection table to determine the required
thickness of the shim (Sp).
Pinion gear shim selection table
Select the shims from the pinion gear shims of different
thickness to obtain the required thickness (Sp) by
combining the shims.
Pinion gear shim type table
HOW TO READ SHIM SELECTION TABLE
When the engagement mark on the gear case housing
is C and the tolerance is -0.05 mm (-0.002 in), the shim
selection table shows that the required shim thickness
is 0.55 mm (0.022 in). (See the table shown below).
Pinion gear shim selection table
HOW TO SELECT SHIM COMBINATION
To obtain 0.55 mm (0.022 in) of shim thickness,
combine one gear shim A, one gear shim B, and one
gear shim C, or combine four gear shim A and one gear
shim B.
